Abstract (en)

The invention relates to a method (10) for operating an MRI device (1), the MRI device (1), and a corresponding computer program product (10) and storage medium (8). In the method (10) image data is acquired using a spin echo sequence with an additional readout (23, 26, 27) per pulse train (18, 19, 20) for acquiring correction data (21, 25). By comparing subsequent correction data (21, 25) of later pulse trains (18, 19, 20) to reference data acquired during a first pulse train (18, 19, 20) of the sequence a difference indicating a parameter shift is determined. A corresponding compensation is then automatically determined in dependence on the difference and is applied to a set of predetermined parameters for at least a respective next pulse train (18, 19, 20) and/or to the image data acquired in at least a respective next pulse train (18, 19, 20) of the sequence.
